The materials which we employ for this purpose are powdered metals, such as chips or filings, or

metal foils of any kind, ground ores or metal-- lie powders of any kind, powdered earths of any kind, or silicious substances, powdered glass, and powdered sands of any kind. These ingredients weapply, either singly or combined in suitable proportions, to the adhesive substance previously applied to the glass, according to the desired color or effect desired to be produced, and by means of said ingredients,

low or otherwise.

Having thus fully described our invention, we wish to secure by Letters Patent, and claim 1. The within-described process of decorating glass, the same consisting in applying to the rear or inner surface of the glass,through the medium of an adhesive coating, a uniform backing of the within-described powdered or fragmentary mineral substances, substantially as and for the purpose described.
